Two quotes for the exact same house can differ by thousands of pounds, yet neither company will volunteer an explanation. This is one of the most common, and most frustrating, experiences homeowners face when replacing windows in the UK. The reason is not always that one company is overcharging or cutting corners.

The 1930s semi-detached is arguably Britain’s most beloved house type. Stretching across suburban streets from Surrey to Salford, these interwar homes account for a substantial slice of the UK’s housing stock, and their distinctive architectural character, wide bay windows, geometric leaded lights, generous frontages, and that unmistakable horizontal emphasis, has given entire neighbourhoods their identity […]

Single-glazed windows lose heat roughly ten times faster than a well-insulated wall. Even in homes with double glazing, windows remain the weakest thermal link in the building envelope, and for millions of UK households still living with ageing frames, poor seals, or original single-pane glass, that weakness translates directly into higher heating bills every winter. […]
That familiar sight of a cloudy, milky haze sitting stubbornly between your window panes is one of the most frustrating things a homeowner can encounter.

Burglary remains one of the most disruptive crimes a household can experience, and windows represent the most common point of entry in domestic break-ins across England and Wales.

A full house of uPVC double glazed windows typically costs between 4,000 and 8,000 pounds for a three-bedroom semi-detached house. Individual windows range from 300 to 800 pounds depending on size and opening style. Prices include supply, fitting, and building regulations certification.

Glazing is also standard-rated for VAT at 20%, as HMRC lists double and secondary glazing as excluded from the energy-saving materials zero rate.
